Modes of Operation

The RediSTATION has 4 modes of operations: Powerup / Reset Mode,
Idle Mode, Run Mode, and Error Mode.

Powerup/Reset Mode

During a powerup or reset, the RediSTATION:

1. Clears outputs (turns outputs off) and cycles the LED indicator

through solid red, green and off. The LED remains off until the
test is completed.

2. Performs powerup diagnostic tests including:

-

EPROM checksum test

-

RAM read/write test

-

Watchdog timer test

-

Serial number verification

If any test fails, the outputs remain off and the LED shows solid
red. You must cycle power to recover from a powerup
diagnostic test failure. Repeated failures indicate a faulty unit.

3. Reads and stores the DIP switch settings.

Important: Changes to DIP switch settings are allowed only in
powerup or reset mode. Changes to DIP switch settings under
power cause an error.
